发明名称 CURRENT OUTPUT TYPE OF SEMICONDUCTOR DEVICE, SOURCE DRIVER FOR DISPLAY DRIVE, DISPLAY DEVICE, AND SIGNAL INPUT OUTPUT METHOD
摘要 To provide a current output type semiconductor circuit, a drive device for display, a display device, and a current output method that can control an increase in a circuit size to be lower even if the number of output bits of a current driver is increased. A current output type semiconductor circuit, including first current source groups 241a and 241b, includes first unit transistors of outputting a predetermined current and output lower order N (N is a natural number) bits; and second current source groups 242a, 242b, 242c, 242d, 242e, and 242f that include second unit transistors of outputting a current larger than that of the first unit transistors and output higher order M (M is a natural number, (N+M)>=3) bits.
